koher 02-Apr-18 09:53 AM

@Kishikawa Katsumi そういえば https://swift-playground.kishikawakatsumi.com/ の初期コードの import Foundation がなくても良いように見えるのが気になってたんですが、これは Fundation が import できることを示すためとかでしょうか？

Kishikawa Katsumi 02-Apr-18 09:54 AM

あまり深い意味はないんですけど、いういう意図もあります。あとは見栄えとか。

koher 02-Apr-18 09:58 AM

もしかしたらコードを修正する過程の消し忘れかもとも思ったので、 Foundation の何かを使ってたらわかりやすいかもしれません。 round とかの関数だと使いやすそうです。

Kishikawa Katsumi 02-Apr-18 10:04 AM

そうですね。ちょっと考えてみます。

norio_nomura 02-Apr-18 10:07 AM

Docker内の環境のリソースの使用を制限した方がいいかなという気もしますが、どうですかね？今は時間制限も大して厳しくはないし、踏み台的な使い方がされてしまったりするのはありそうと思っています。

koher 06-Apr-18 03:16 AM

ネットワークにはアクセスできないようにした方がいいかもしれませんね。

Kishikawa Katsumi 06-Apr-18 03:25 AM

そうですね。それを制限しておけば外に迷惑をかけることはないはず？

koher 06-Apr-18 03:29 AM

Docker 詳しくないですが、隔離されてるのでそのはずかと。あとは CPU とかメモリの使用量を制限しておけば、時間制限もあるし、何されても大体大丈夫そうな気がします。

Kishikawa Katsumi 08-Apr-18 05:01 AM

@taketo1024 デフォルトでSwiftyMathをリンクするようにしました。importだけ書けばOKです。

他の人には影響ないと思いますが、もし何か問題を見つけたら教えてください。デフォルトのオプションを与えているという仕組みなので、--optionsを別の何かで上書きすると以前と同じバニラのSwift環境が使えます。 SwiftyMathをリンクしているのは今の所stable (== 4.1)のみです。

上で私間違ったこと書いてて、arc4randomは明示的なシードの初期化がいらないってだけで暗号論的に安全な乱数を返すわけではないですね

taketo1024 09-Apr-18 06:01 AM

HISTORY The original version of this random number generator used the RC4 (also known as ARC4) algorithm. In OS X 10.12 it was replaced with the NIST-approved AES cipher, and it may be replaced again in the future as cryptographic techniques advance. A good mnemonic is ``A Replacement Call for Random''.

訳すと RC4(ARC4とも言う)アルゴリズムの実装だけど OS10.12で AESに変わったし、後にまた変わるから、 A Replacement Call For Random の略として覚えると良いよ (edited)

Unsafe bit castでDogをCatに改造すると

omochimetaru 09-Apr-18 07:53 AM

同じシグネチャのメソッドならそのまま呼び出せるみたいなね。

tarunon 09-Apr-18 07:55 AM

var foo: Foo { return x } と func foo() -> Foo { return x }の扱いが、前者はフィールドとして定義されているのでunsafeBitCastしても同じものが呼ばれるが、後者は実質的には第一引数にselfを与えるstatic funcなのでunsafeBitCastで違うものが呼ばれる、とか。

tarunon 09-Apr-18 08:25 AM

var foo: Foo { return x } じゃなくて let foo: Foo = x だった。

letで定数として定義しても、値に対してのプロパティなら、ちゃんと値に対してメモリ確保されてるのがわかる。正しいと思います。

omochimetaru 09-Apr-18 08:30 AM

structのメソッド呼び出しは非仮想だから cat. の型に関係なく固定でcat用のメソッドが呼ばれてますね (edited)

unsafeBitCastの使用自体が正しくないから、その時点で何も正しくないともいえるし、その行を正しいとみなすなら何も壊れてない

guard関係ある？hogeの呼び出しで落ちるというだけじゃない。

あー、guardは関係ないか。

①の行で落ちるのがおかしくない？

hoge()の中で落ちるんじゃないの　って感じ

SwiftBotに、同じソースを複数のSwiftバージョンで実行した結果を一度で得られる仕組みがあると、バージョンによる挙動の違いを示し易くなる。

Kishikawa Katsumi 12-Apr-18 02:58 AM

バージョンを複数渡せるようにしますかね。

child_process.execFileでよさそうですね。

--version=stable...latestや--version=3...4.1のように書けたらいいのかな？

omochimetaru 12-Apr-18 03:06 AM

Kishikawa Katsumi 12-Apr-18 03:11 AM

確かに。 --version="4.0.3, 4.1, latest" こんな感じかな。 (edited)

なんとなくstable...latest で上のように展開されるという思い込みと、カンマだとおそらくクオートで囲む必要がありそうで、それを避けたかった感じ。

docker内で起動されるスクリプトへ全部渡ってしまうならOKかな。

Kishikawa Katsumi 12-Apr-18 03:42 AM

そうですね。そこが一番問題のコードです。

のむらさんの指摘はdocker runコマンドの実行をオプションに渡す文字列で止めて、かつそのあとに任意の処理が実行できるんじゃないなということですよね。たぶんできたんじゃないかな。

norio_nomura 12-Apr-18 03:53 AM

こうすると、script.shを実行した上で別途testってファイルを作れます。

const exec = require('child_process').exec; const options = "& echo hello>test"; exec(['sh', 'script.sh', [options].join(' ')].join(' '));

joinでつなぐやり方はsandbox.jsで使われてるのと同じ。

execに渡す時にもう一回文字列化してるから

そこで配列要素としての区切りが消えてる

Kishikawa Katsumi 12-Apr-18 03:58 AM

dockerに入れたnodeで実行しようと考えたきっかけです。

Kishikawa Katsumi 12-Apr-18 03:59 AM

じゃあまあ怪しい文字列をBanするのは必要かな。

私もそうしたいんですけどね。Docker in Dockerがちょっと大変なのがやっぱり気になりますね。

norio_nomura 12-Apr-18 04:00 AM

文字列化しないでexecFileを使えばサニタイズ無くても大丈夫かも？ → しかしrun.shの中での扱いは大丈夫？といった流れ。 (edited)

Kishikawa Katsumi 12-Apr-18 04:01 AM

run.shの中は一番怪しい。

omochimetaru 12-Apr-18 04:01 AM

Mac環境でも実行できると便利だなーと思っていて、 https://www.macstadium.com/ を共同で使うという企画を進めようかなと。

Linuxでのbacktraceをもうちょっとマシなものにしようとしたけど、Herokuのコンテナ内では無理だった。

Kishikawa Katsumi 16-Apr-18 03:16 PM

Swiftをシンボル付きでビルドするんですよね？

norio_nomura 16-Apr-18 03:18 PM

いえ、coreダンプを利用する方法と、backtraceのログテキストをpythonスクリプトで整形する2通りがあります。 https://github.com/gmilos/swift/blob/master/utils/symbolicate-linux-fatal

gmilos/swift

swift - The Swift Programming Language

coreダンプを利用する方法 https://gist.github.com/norio-nomura/6654bea680baa61bb326d0ef4869615a

Symbolicate crash from core on Linux

lldb swift -c core -o bt -bでバックトレースを作れる。

symbolicate-linux-fatal の方は実際に成功していないけど、 symbolicate-linux-fatal app crash.log的な使い方をするぽい。

どっちもlldbの実行に依存してる。

Herokuのコンテナ内ではlldbを使えなかった。

あ、Docker Imageで設定しているやつか。それでも今の私のやり方より良いですね。

ボタンの機能はDiscordにはないっぽいな。

norio_nomura 19-Apr-18 08:22 AM

デプロイボタン付ければ動くかどうかはまだ試してないな…

今は一つのリポジトリに3つのブランチがあって、それらが3つのHerokuアカウントにDeployされてる感じ。

ボットをビルドするSwiftコンパイラと、Discordでのリクエストをビルドするコンパイラが同じ、かつ同じコンテナ内で動くので、ネットワークアクセスとかも出来てしまいます。

なんとか出来ないか調べましたが、諦めました。

Kishikawa Katsumi 19-Apr-18 08:33 AM

まあ私のと違ってREST APIとかはないんですよね。何かするにはここに投稿する必要があるんですよね。 (edited)

norio_nomura 19-Apr-18 08:35 AM

そう。workerでDiscordのクライアントが動いてて、何もEXPOSEしていません。 (edited)

HerokuのDockerコンテナはEXPOSEサポートしてなかった。 https://devcenter.heroku.com/articles/container-registry-and-runtime#unsupported-dockerfile-commands

何かクラッシュするバグを仕込んでしまったぽい…

これ、テストとか頑張れば書けるのかな…

Kishikawa Katsumi 19-Apr-18 08:47 AM

私もややこしくなってきたので、１メソッドで書き下していたのを分割して、意図しない影響を与えてないかを確認する正常系のテストを書こうと思ってます。それは難しくないはず。

その次に書けたら意地悪な投稿でも問題が起きないようにある程度異常系のケースを書いて、って感じですね。

それ以上は今のところ何かあったら再起動でいいので諦めていいんじゃないですか。

たぶん、他の人が押してもビルドしなくなったと思います。

回数の問題は推測だけど再ビルドはパラメータをちょっと変えて再帰的に呼び出すみたいな処理になってるので、リアクションを受けた時のコールバックのクロージャがどんどん増えてるんじゃないかと。これはちょっと設計を見直しているのでそこで直せるはず。

お、~~行単位~~行区切りで自動分割投稿する仕組みがあるのかな？>discord.js (edited)

Kishikawa Katsumi 05-May-18 04:32 AM

discode.jsはsend(contents, options)みたいなAPIになっていて、optionsに{split: true}で自動的に分割してくれます。

norio_nomura 05-May-18 04:32 AM

なるほど。

Kishikawa Katsumi 05-May-18 04:32 AM

ただ、いつも思ったよりたくさん出るので、今のところ使いどころがありません。。。

GitHubのTags APIで2018-05-02-aが出てこないのなんでかな。 curl https://api.github.com/repos/apple/swift/tags

norio_nomura 05-May-18 05:41 AM

GraphQLだと返ってきます。

{ "data": { "repository": { "refs": { "pageInfo": { "endCursor": "MTAw", "hasNextPage": true, "startCursor": "MQ==" }, "tags": [ { "name": "swift-4.2-DEVELOPMENT-SNAPSHOT-2018-05-02-a" }, { "name": "swift-4.1.1-RELEASE" }, { "name": "swift-DEVELOPMENT-SNAPSHOT-2018-04-25-a" }, …

Kishikawa Katsumi 05-May-18 05:41 AM

@norio_nomura Thanks. GraphQL使ってみます。

REST APIはObsoleteになっていくのかなあ。

norio_nomura 05-May-18 05:43 AM

ちなみにクエリはこんな感じ。

query ($owner: String!, $name: String!, $cursor: String = "") { repository(owner: $owner, name: $name) { refs(refPrefix: "refs/tags/", first: 100, after: $cursor, orderBy: {field: TAG_COMMIT_DATE, direction: DESC}) { pageInfo { endCursor hasNextPage startCursor } tags: nodes { name } } } }

Query Variables:

{ "owner": "apple", "name": "swift", "cursor": "" }

(edited)

ページングはcursorに前のendCursorを渡す。

curl https://api.github.com/repos/apple/swift/tagsでタグ一覧を取得する方法は、そもそもAPIドキュメントに載ってないので、非公式な動作なのかも？ https://developer.github.com/v3/git/tags/

というか、ドキュメントに載ってなかったのでGraphQLを使うようにしました。

Kishikawa Katsumi 05-May-18 05:49 AM

いや、ドキュメント見て作ったリクエストなのでどこかに載ってるはずです。

Releases APIからTags APIに行って、そこに載ってたと思います。

https://developer.github.com/v3/repos/#list-tags

norio_nomura 05-May-18 05:50 AM

なるほど、ありがとうございます。

Kishikawa Katsumi 05-May-18 06:05 AM

Kishikawa Katsumi 08-May-18 04:15 AM

ちょっと試しでRichEmbedというのを使ってみました。１つのメッセージにできるので、編集等があった時の管理が簡単になりました。ただEmbedは25個/メッセージですけど1Embedが1000文字までなので返せるOutputは半分になるところがデメリットですね。

バージョン違いで壊れるのデモしたかったけどできなかた

Kishikawa Katsumi 16-May-18 11:20 AM

外部フレームワークは特定のバージョンにしか入れてないんですよね。予定はあってやり方も頭の中にはあるんですけど。

特に過去のバージョンにリンクさせるにはまずSwift 3.xで動くバージョンはどれなのかというところをやらないといけないのでそれが面倒に思っています。Snapshotで動かすのは最新のリリースかmasterでいいと思うんですけど。

Kishikawa Katsumi 16-May-18 11:31 AM

今考えてるのは https://github.com/kishikawakatsumi/swift-playground/tree/master/Libraries/All ^ ここを4.1.1/Libraries/*、 3.0.2/Libraries/* ... のようにディレクトリでバージョニングして、それぞれのPackage.swiftでそのバージョンで使うライブラリを指定するって感じに改修ですね。そうすると使う方（Botのプログラム）で -L ${SWIFT_VERSION}/Libraries/All のように切り替えられるのでうまくいくと思うんでなんだったらPRしてくれると

です (edited)

ボット関連の通知(DockerHubへのpush, Herokuのbuild)は、webhook経由で管理用Discordチャンネルへ投稿して、それをiOSのプッシュ通知で受け取ってる。

ボットがオフラインになったかどうか？の監視は、ボットを監視するボットを作って、それにメールを送らせるとかさせれば良いのかな。

PathConstructor<T1, PathConstructor<T2, T3>> を Path<T1, Path<T2, T3>> に変換するために再帰させたいなーと

kateinoigakukun 20-Jun-18 03:52 AM

@koher ちょっと僕の言葉が足りてなかったです。 Tnまで再帰させたかったんで、parameterized exを使うとこんな感じです

struct Path<T1, T2> {} struct PathConstructor<T1, T2> { typealias PathType = Path<T1, T2> } extension<T3, T4> PathConstructor where T2 == PathConstructor<T3, T4> { typealias PathType = Path<T1, T2.PathType> } extension PathConstructor { func create(path: [String]) -> PathType { fatalError() } }

@N. notifyって、そのグループのenter数が1->0になるタイミングを待つんじゃないですかね？

そのコードだと、関数aの呼び出しがグローバルキューに投げられているので、

あいや、いいのか、sleepしているから、必ず３つのenterが先行しているんですね。

ん

1つめのenterよりもはやくnotifyして即抜けしているけど

printの前後順だけはすり替わってる？

おお、なるほど。納得できました。ありがとうございます！

omochimetaru 04-Sep-18 07:19 AM

これ、従来は、

modを呼び出す前にテンポラリな変数が作られてmodを呼び出した後

setterを改めて呼び出して処理結果を格納していたんだけど

modifyアクセサだったら、そのようなテンポラリな値を作る事なく、一発で内部に（ポインタで）書き込める (edited)

Kotlin のは、単に max 超えてるのは全部 max に丸められるだけだった。

Long → Int とかと同じで上位ビット切り捨てかと思ってた。 (edited)

Double のビット数考えればしょうがないか。

変換できないのが？クラッシュするのが？

rintaro 21-Sep-18 09:15 AM

ビット数により精度を保てないが故にオーバーフローしてクラッシュするのが、ですね。

koher 21-Sep-18 09:17 AM

Int.min だとクラッシュしないのが微妙ですね。丸め方向の偶然に挙動が委ねられてる感が。

それは、 protocol P に対して P型(existential)それ自体は P に準拠しないから

<Failure : Error(これはプロトコル) > にたいして Failure == Error ( これはExistential)

を制約しても意味ないから、間違ってるよってエラーです

このプロポーザルによって、

Error(exis)型それ自体もErrorプロトコルであるように、

変更されるから

その言語仕様の変更とセットじゃないと意味がないコード。

Adam and Xiaodi have it correct, and it’s always possible to get the effect you want by adding an overridable method to mySuperClass (something like ‘defaultStatement()’).

omochimetaru 30-Jan-19 12:33 AM

なんで2

ああ、utf8で１つ戻って文字の途中に突っ込んだのか

swift4では文字頭までもどったから2で、swift5はutf8の位置がモテるから1か

これはこれで良いのでは？

norio_nomura 30-Jan-19 12:59 AM

どっちが正しいのかはおいても、挙動が変わってるのが。

omochimetaru 30-Jan-19 01:06 AM

やっぱり5の挙動が変に思えてきました

いちどbeforeとafterはStringになってるのに

afterが保持してるのはutf8の後続バイトだ

StringはCharacterに分けられる場所でしか切り出せないのが良いと思う

norio_nomura 30-Jan-19 01:25 AM

この変更があっさり入っているという事は、この挙動をテストするコードがずっとなかったって事？

これはSwift 5のString.UTF8View.index(before:)と同等の挙動。

norio_nomura 31-Jan-19 12:32 AM

https://bugs.swift.org/browse/SR-9820

とりあえず、Swift 4とSwift 5でString.UTF16ViewとString.UTF8View両方のindex(before:)の挙動が違う。

omochimetaru 31-Jan-19 01:42 AM

Swift4の場合は　末尾のU+1F466がサロゲートペアでちぎれて、どちらも表示は不正文字FFFDになるが、ちぎれたまま保持されてて、くっつけると繋がって戻る Swift5の場合は　末尾のU+1F466がペアを保ってちぎれて、どちらもCharacter境界をたもってて、countは2になっていて、くっつけるとつながって戻るという感じか (edited)

これも4と5で挙動がちがう。 (edited)

挙動が一貫してないよね。

omochimetaru 31-Jan-19 01:44 AM

Swift5においてUTF-16に限っては、Character境界までインデックスが畳み込まれる挙動が追加実装されたけど、UTF-8は不正位置でちぎれる

string.unicodeScalars[index] の場合はunicode scalar

Swift 5ではUTF16View.IndexがUnicodeScalarの境界に合わせられる様になった。

omochimetaru 31-Jan-19 01:53 AM

内部表現ではない方のindexが、unicode scalar境界に畳み込まれるという意味では

一貫している？

norio_nomura 31-Jan-19 01:55 AM

UnicodeScalar boundaries are: respected by: String.UTF8View.index(before:) on Swift 4 String.UTF16View.index(before:) on Swift 5 not respected by String.UTF16View.index(before:) on Swift 4 String.UTF8View.index(before:) on Swift 5

UTF-16からUTF-8へ切り替わった事で、挙動も入れ替わってる。

norio_nomura 31-Jan-19 02:06 AM

内部表現ではない方のindexが、unicode scalar境界に畳み込まれるという意味では一貫している？

そう言える。ランタイムの内部表現に依存してるかどうかまでは確かめてないですが。

Swift 5で試した限り、swift-corelibs-foundationだと内部表現をUTF-16にする方法は見つからず。Apple Platformだと一部のNSString APIを使うとUTF-16になる。

omochimetaru 31-Jan-19 02:09 AM

ああ、そうすると実行時に変化もするのか・・

norio_nomura 31-Jan-19 02:16 AM

以前試した時は、macOSでString.init(contentsOfFile:encoding:)を使うと内部表現がUTF-16になってた。

見分け方は、String.UTF8View.withContiguousStorageIfAvailable(_:)を使った時、渡したクロージャが呼ばれたら内部表現はUTF-8、呼ばれなかったらUTF-16

ForumのType Safety of String IndicesについてのMichael_Ilsemanさんの返答を読んでると、UTF8View.index(before:)とUTF16View.index(before:)は使ってはいけないモノだと言われている様に思えてくる。

norio_nomura 31-Jan-19 03:19 AM

ランタイムの内部表現に依存してるかどうかまでは確かめてないですが。

依存してるぽい。

このコードをmacOSで実行すると、stringUTF16Backendを使うとtest()内でクラッシュする。

- String.UTF8View, String.UTF16Viewを使ったString.Indexの操作は、UnicodeScalarsの境界に合わないIndexを作る場合がある。(仕様) - Swift 5はUnicodeScalarsの境界に合わないIndexを使ったRangeでSubstringを作ると、クラッシュする場合がある。(バグ) (edited)

そんな感じか。

norio_nomura 31-Jan-19 06:03 AM

@rintaroさんの

https://bugs.swift.org/browse/SR-6161 これを思い出しました。

を読んで、試して、ようやく理解したぽい。問題となるのはindex(before:)の挙動ではなく、String, UTF8View, UTF16Viewそれぞれのsubscriptがunicode scalarsの境界に合わないIndexを持つRangeをどう扱うか、が変わっている事なのね。 (edited)

norio_nomura 31-Jan-19 06:22 AM

SR-6161の結果がSwift 4とSwift 5で変わってしまうのは、境界に合わないIndexが指すものはU+FFFDとして扱わなければいけないのだけど、境界に合う合わないの判定がUnicode Scalarを基に行われていないからな気がする。

Slava Pestov (@slava_pestov)

The Swift compiler accepts this code: let fn: @pseudogeneric () -> () = {} (This is a bug; @pseudogeneric is only meant for SIL mode, but due to an oversight it’s accepted and ignored during normal parsing too)

Playground程度なら遊んでる家のMacでできるけど、AppKitはともかくUIKitはうまいこと実行するのが難しそうだな。

omochimetaru 17-Apr-19 05:32 PM

確かにPlaygroundは実行できてもコマンドラインバイナリとして実効する手段が無いですね。ライブラリにしてシミュレーター上でテストケースを実行するとかはできるけど

UIKitの部分とかはOSに入ってる想定だから、そうなるのか。なるほど。

norio_nomura 18-Apr-19 12:00 AM

install_name_toolでUIKitのパスを変えたら、@rpath/libswiftCore.dylibをロードできないと言われた。

で、rpathを設定したらUIKitにリンクされてるDocumentManagerをロードできないと言われ、ここで「実行時の環境を変えないとダメだ。」となりinstall_name_toolを使う方法は終了。

バイナリをシミュレーターコンテナ？のなかで起動しないとだめそうですね

norio_nomura 18-Apr-19 12:06 AM

simctlはアプリケーションバンドルを起動するコマンドしかないから、chroot的な仕組みを使うしか無さげ。

playground/iosとかはどうやってるんだろうなあ

norio_nomura 18-Apr-19 12:14 AM

そのシミュレーターに対して、任意のコードを送り込める所の仕組みが知りたい

norio_nomura 18-Apr-19 12:19 AM

アプリケーションバンドルを作成してるんじゃないかな。

norio_nomura 18-Apr-19 12:28 AM

omochimetaru 18-Apr-19 12:36 AM

norio_nomura 18-Apr-19 12:38 AM

rpath設定は必要。

$ pbpaste import UIKit print("UIKit") $ pbpaste|swiftc -sdk $(xcrun --show-sdk-path --sdk iphonesimulator) -target x86_64-apple-ios12.2-simulator - -Xlinker -rpath -Xlinker $(xcrun --show-sdk-platform-path --sdk iphoneos)/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/swift $ DYLD_FRAMEWORK_PATH=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/Frameworks:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/Frameworks DYLD_FALLBACK_LIBRARY_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib DYLD_ROOT_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot DYLD_FALLBACK_FRAMEWORK_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks DYLD_LIBRARY_PATH= ./main UIKit

まあiPhoneのUIを実際に使うコードは動かないけど、UIKitをリンクして動かすことは出来た。

omochimetaru 18-Apr-19 12:43 AM

フルパスで参照してるフレームワークも差し替え効くんですね DYRD_ROOT_PATHがそれか？

norio_nomura 18-Apr-19 12:43 AM

DYLD_*環境変数は、playgroundが実行してるアプリケーションに渡されてたものを全部記述しました。 (edited)

omochimetaru 18-Apr-19 12:44 AM

なるほど！どうやって読み取ったんですか？

norio_nomura 18-Apr-19 12:45 AM

アクティビティモニタでプロセス名を調べps axe|grep プロセス名ですね。

該当プロセスとgrepのプロセスの情報が出ます。 (edited)

omochimetaru 18-Apr-19 12:48 AM

psのe知りませんでしたなるほどーー

norio_nomura 18-Apr-19 01:14 AM

DYLD_FALLBACK_LIBRARY_PATHにusr/lib/swiftの分も追加すれば、rpath指定無しでいける。

$ ROOT_PATH=$(xcrun --show-sdk-platform-path --sdk iphoneos)/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot && \ DYLD_FALLBACK_FRAMEWORK_PATH=$ROOT_PATH/System/Library/Frameworks \ DYLD_FALLBACK_LIBRARY_PATH=$ROOT_PATH/usr/lib:$ROOT_PATH/usr/lib/swift \ DYLD_LIBRARY_PATH= \ DYLD_ROOT_PATH=$ROOT_PATH \ ./main

(edited)

omochimetaru 18-Apr-19 01:21 AM

なるほど

norio_nomura 18-Apr-19 01:36 AM

DYLD_LIBRARY_PATH= は無くても良さげ。simctlとjqで.simruntimeの場所を取得する方法に書き換えると

$ ROOT_PATH=$(xcrun simctl list -j runtimes ios|jq -r '.runtimes[-1]|.bundlePath')/Contents/Resources/RuntimeRoot && \ DYLD_FALLBACK_FRAMEWORK_PATH=$ROOT_PATH/System/Library/Frameworks \ DYLD_FALLBACK_LIBRARY_PATH=$ROOT_PATH/usr/lib:$ROOT_PATH/usr/lib/swift \ DYLD_ROOT_PATH=$ROOT_PATH \ ./main

が一番シンプルな記述かな。 (edited)

まとめると

$ pbpaste import UIKit protocol Component: UIView { associatedtype Model func activate(with model: Model) func deactivate() } class ImageComponent: UIImageView, Component { typealias Model = UIImage func activate(with model: ImageComponent.Model) { image = model } func deactivate() { image = nil } } print("UIKit") $ pbpaste|swiftc -sdk $(xcrun --show-sdk-path --sdk iphonesimulator) -target x86_64-apple-ios12.2-simulator - $ ROOT_PATH=$(xcrun simctl list -j runtimes ios|jq -r '.runtimes[-1]|.bundlePath')/Contents/Resources/RuntimeRoot && \ DYLD_FALLBACK_FRAMEWORK_PATH=$ROOT_PATH/System/Library/Frameworks \ DYLD_FALLBACK_LIBRARY_PATH=$ROOT_PATH/usr/lib:$ROOT_PATH/usr/lib/swift \ DYLD_ROOT_PATH=$ROOT_PATH \ ./main UIKit

omochimetaru 18-Apr-19 01:41 AM

xcrun simctlってJSONで出してくれるオプションあるんですね。

norio_nomura 18-Apr-19 01:41 AM

Kishikawa Katsumi 18-Apr-19 01:50 AM

norio_nomura 18-Apr-19 01:51 AM

無くすと、-Xlinkerで-ios_simulator_version_minを指定する必要が出てきそうです。

DataProtocol.lastRange(of:) の件、apple/swiftの（つまりDarwin用の）swift-5.0-branchだけ正しい状態だったので、まずapple/swiftのmasterに修正のPR出してみました https://github.com/apple/swift/pull/25065 (edited)

DataProtocol.lastRange(of:) is correct in swift-5.0-branch, but not in master and swift-5.1-branch. The changes are from #21292 (d7fcb87).

これが通ればswift-5.1-branchと、foundationのmasterと5.0-branchにも修正出す流れで。

omochimetaru 09-Jul-19 01:34 AM

FoundationとかUIkitの関連APIを全部2重で生やさないといけないけど

実装されているならApple版は要らないね

どっちかというと、すでにapple版があるのにOSS版の実装が完全に整うかどうかって点で

実現しない気がする。

てか挙動同じならなおさらどっちでもいいので作る必要がない

あ、でもソース付きデバッグできるとかあるかも。

ストリーム系は特にややこいし。

やはりapple系ではCombineでしょうね。それになれた開発者がlinux開発に行くときに使うかも？ってくらいになりそうでしょうか。

t.ae 29-Aug-19 03:30 AM

確かもとはcallだったはずｗ

omochimetaru 29-Aug-19 03:30 AM

最初はcallに落ち着きそうだったんだけどcallFunctionになってcallAsFunctionになっていった

メソッド名無しとか

funcの代わりに新しい予約語としてcallで定義するとかの案もありました。 (edited)

Kishikawa Katsumi 29-Aug-19 03:31 AM

まあでもコールサイトの問題だから影響はないのか。

func call()でも

omochimetaru 29-Aug-19 03:32 AM

使う側からするとどうせ見えないっすね

でも僕はfunc callが良かったな・・・ (edited)

Kishikawa Katsumi 29-Aug-19 03:33 AM

まあこのマニアックな言語仕様を知らなかったらわからんというのはある。 func call() だと

omochimetaru 29-Aug-19 03:33 AM

@callableとかもあったな。

Kishikawa Katsumi 29-Aug-19 03:34 AM

Codableとかはなんとなく知識の延長でわかる気がするけど func callAsFuncion() は閃きが必要じゃないか。

@callableはいいんじゃない。

t.ae 29-Aug-19 03:34 AM

特に違和感なくcallAsFunction使ってましたけど仕様知らなかったら完全に意味不明ですね……

omochimetaru 29-Aug-19 03:34 AM

特殊な事が起こる感があってググりやすそうですよね

アトリビュート増やしまくるのやめてくれ〜みたいな反論もあった

結局コアチームの言うcallがダメな最大の理由は、それまでにたまたま使われたcallに新しい意味が衝突するのは良くないって事だったと記憶 (edited)

つまりこの仕様が出るのがSwift2.0とかだったらcallになった可能性もあるって事で

保守的になったなあ、と思った。

Kishikawa Katsumi 29-Aug-19 03:37 AM

callAsFunctionでも一緒だけど、その辺は柔軟だなあ

omochimetaru 29-Aug-19 03:37 AM

そうですね、確率的に多いだろう、って話ですね (edited)

Kishikawa Katsumi 29-Aug-19 03:38 AM

まあ本質的に一緒だけどcallよりだいぶマシというのはわかります。

omochimetaru 29-Aug-19 03:38 AM

それでcallFunctionが出て、それ英語的に命名がおかしい、ってなってcallAsFunctionになっていった。

なるほど〜〜〜

UnsafePointer<T>の.pointeeはmemcpy semanticsだからアライメントエラーは起きないんだ

UnsafeRawPointerの.loadが本当の生のポインターデリファレンスで、こっちはエラーが起きる。

知らなかった。

hironytic 30-Oct-19 02:49 AM

知りませんでした。。。

omochimetaru 30-Oct-19 02:50 AM

つまり、メモリレイアウトレベルのハードキャストをしたいだけの状況であれば、UnsafePointer<T>を使う限りアライメントのことは忘れてよいっぽいですね

一方で、最高速度を求めてメモリ操作したいのであれば、非効率な場合に死んでくれるUnsafeRawPointerを使ったほうが良い・・・？

なんかそれも微妙な話だな。型ないし。

hironytic 30-Oct-19 02:52 AM

あ、でも、これってfatalErrorが出てるだけ？もしかして、fatalErrorが入ってなければ単に落ちないかもだけな可能性もある？

最適化オプションで挙動が変わったりとかしないですかね。

omochimetaru 30-Oct-19 03:49 AM

fatalErrorが呼ばれているので本当に処理系からメモリ違反シグナル等が飛んでいるわけではないですね。でもfatalErrorに関しては-Ouncheckedでも無効化しないです。 uncheckedで消せるのはprecondition。 (edited)

ぼくもこのテクニック使いたいので。

tarunon 06-Jan-20 02:30 PM

このコミットはこのまま置いておこう

kateinoigakukun 06-Jan-20 02:30 PM

tarunon 06-Jan-20 02:31 PM

もしかしたら、呼び出し時に型を参照できなくなってるかもしれないですね。その場合AnyEquatableでもダメだ (edited)

tarunon 06-Jan-20 02:49 PM

@swift-5.1.5

protocol AnyEquatableBase { associatedtype Value var value: Value { get } func isEqual(to other: Self) -> Bool } extension AnyEquatableBase { func isEqual(to other: Self) -> Bool { false } } extension AnyEquatableBase where Value: Equatable { func isEqual(to other: Self) -> Bool { value == other.value } } struct AnyEquatable<T>: AnyEquatableBase { var value: T } print(AnyEquatable(value: "abc" as Any).isEqual(to: AnyEquatable(value: "abc" as Any)))

swift51 BOT 06-Jan-20 02:49 PM

false

tarunon 06-Jan-20 02:49 PM

こういうことだと思うんです

やっぱり呼び出し元でEquatableが見えてないとAnyEquatableを作った瞬間にfalse側に倒れちゃいますね。上位から伝播させなければいけない

@swift-5.1.5

protocol AnyEquatableBase { associatedtype Value var value: Value { get } func isEqual(to other: Self) -> Bool } extension AnyEquatableBase { func isEqual(to other: Self) -> Bool { false } } extension AnyEquatableBase where Value: Equatable { func isEqual(to other: Self) -> Bool { value == other.value } } struct AnyEquatable<T>: AnyEquatableBase { var value: T } func check<T>(lhs: T, rhs: T) -> Bool { AnyEquatable(value: lhs).isEqual(to: AnyEquatable(value: rhs)) } print(check(lhs: "test", rhs: "test"))

swift51 BOT 06-Jan-20 02:54 PM

false

omochimetaru 06-Jan-20 02:59 PM

AnyEquatable<Any>になっちゃってると、Value: Equatableの評価がAnyに対して行われてしまって、

Anyに入ってる実際の値の型では処理されないってこと？

tarunon 06-Jan-20 02:59 PM

そうです

omochimetaru 06-Jan-20 03:00 PM

なるほど。う～ん、それは正しい挙動だな。

Anyにしまうことで型情報が消去されたと。

tarunon 06-Jan-20 03:00 PM

Generics内部でなんでこうなるかは謎だが

kateinoigakukun 06-Jan-20 03:00 PM

そうかなるほど

tarunon 06-Jan-20 03:01 PM

うわうわうわうわう

@swift-5.1.5

protocol AnyEquatableBase { associatedtype Value var value: Value { get } func isEqual(to other: Self) -> Bool } extension AnyEquatableBase { func isEqual(to other: Self) -> Bool { false } } extension AnyEquatableBase where Value: Equatable { func isEqual(to other: Self) -> Bool { value == other.value } } struct AnyEquatable<T>: AnyEquatableBase { var value: T } func check<T>(lhs: T, rhs: T) { print(AnyEquatable(value: lhs)) print(AnyEquatable(value: lhs).isEqual(to: AnyEquatable(value: rhs))) } func check2(lhs: String, rhs: String) { print(AnyEquatable(value: lhs)) print(AnyEquatable(value: lhs).isEqual(to: AnyEquatable(value: rhs))) } check(lhs: "test", rhs: "test") check2(lhs: "test", rhs: "test")

swift51 BOT 06-Jan-20 03:01 PM

AnyEquatable<String>(value: "test") false AnyEquatable<String>(value: "test") true

tarunon 06-Jan-20 03:01 PM

シュレディンガーの猫みたいな動きをするな

omochimetaru 06-Jan-20 03:02 PM

お～

tarunon 06-Jan-20 03:02 PM

同じ型なのにwtの参照先が違うのはやばいなw

omochimetaru 06-Jan-20 03:02 PM

バグっぽい

kateinoigakukun 06-Jan-20 03:02 PM

いやー、これは無理じゃ無いですかねー

tarunon 06-Jan-20 03:03 PM

Anyで潰れるのは許せると思うんですが

GenericsでStringが渡ったのに潰れるのは微妙では

AnyEquatable<Any>(value: "test")なら良い

kateinoigakukun 06-Jan-20 03:04 PM

checkがWTを受け取るようになってないから現状のABIでは厳しそう

tarunon 06-Jan-20 03:04 PM

ふむー

omochimetaru 06-Jan-20 03:04 PM

ん？TとしてRuntimeにString.selfは渡ってきていて

String.selfからEquatable conformance for StringのWTはダイナミックに取れない？

そうじゃないのか？ AnyEquatable<$T> みたいなものとして静的に解決している？

kateinoigakukun 06-Jan-20 03:06 PM

取れることは取れるんですけど、本来それは呼び出し元でコンフォーマンスを取得してcheckに渡す形になるはずで、checkの中で任意の型に対して毎回コンフォーマンスを取得するのはコストが大きい気がします

omochimetaru 06-Jan-20 03:06 PM

クエリ自体でキャッシュされるはず

kateinoigakukun 06-Jan-20 03:07 PM

それはそうですけど…

tarunon 06-Jan-20 03:07 PM

とりあえずバグレポいってみよう

kateinoigakukun 06-Jan-20 03:07 PM

そうですね

omochimetaru 06-Jan-20 03:07 PM

dup探すのむずそう。

tarunon 06-Jan-20 03:07 PM

きびしーね

omochimetaru 06-Jan-20 03:08 PM

まあとりあえず現状のふるまいとしては

extensionの解決は一般のTでコンパイル時に確定しているってことね

これそうか、

func check3<T: Equatable>(...) {}

tarunon 06-Jan-20 03:09 PM

そうです

omochimetaru 06-Jan-20 03:09 PM

↑これも作っておけばよいのね

kateinoigakukun 06-Jan-20 03:09 PM

そうそう

tarunon 06-Jan-20 03:09 PM

まあそこをオーバーロードで解決が丸いかな

因みに

omochimetaru 06-Jan-20 03:09 PM

めんどいけど対応はできるね

tarunon 06-Jan-20 03:09 PM

挙動からの推測ですが、おもちさんのextensionを使った擬似open existentialで

この壁を突破できる予感があります。少なくともそうでないと、私のコードが動いてる理由がよくわからない。

omochimetaru 06-Jan-20 03:10 PM

たしかに。

tarunon 06-Jan-20 03:10 PM

今回消滅を起こしてる箇所はわかっていて

そこをなんとかできないかこれから試す

あ、擬似open existential、これでもかというほど役に立っています。ありがとう

omochimetaru 06-Jan-20 03:11 PM

ただの

Anyにextensionはやせたっけ

tarunon 06-Jan-20 03:11 PM

だめ

omochimetaru 06-Jan-20 03:11 PM

じゃあだめだ

疑似ってか本物のopenだと思う (edited)

tarunon 06-Jan-20 03:11 PM

Equatable確認したいよprotocolを作れば良い

omochimetaru 06-Jan-20 03:12 PM

ああそっか。

便利だよね

知らないとかけないコード結構ある

僕が呼び方を名付けるとしたら、existential extensionによる間接open、とかかな

tarunon 06-Jan-20 03:13 PM

あ、ダメだった

@swift-5.1.5

tarunon 06-Jan-20 03:14 PM

だめです

kateinoigakukun 06-Jan-20 03:16 PM

Selfの型が静的に決まっちゃうからダメなのかー

tarunon 06-Jan-20 03:17 PM

雑に探した感じ特に無さそうなのでダブってたら閉じてもらおう

omochimetaru 06-Jan-20 03:18 PM

なんか俺が思ったのと違うな　ちょっとやってみる

あー、事前に対象の型を extension Cat: MaybeEquatable {} しておかないといけない。

tarunon 06-Jan-20 03:25 PM

ん、してあると思う

あ、Tにってことか！

omochimetaru 06-Jan-20 03:26 PM

AnyEquatableのTに制約として T: MaybeEquatable した上で

Cat: MaybeEquatable みたいな。

tarunon 06-Jan-20 03:26 PM

おk理解

しかしそこまで行くと使いたいかっていうとウーンだな

omochimetaru 06-Jan-20 03:27 PM

うむ。

結局 check3 をオーバーロードするか

tarunon 06-Jan-20 03:27 PM

MaybeEquatableをpublicにしなきゃいけない、バッちすぎ

omochimetaru 06-Jan-20 03:27 PM

扱いたい型全部にそれを付けるかになる

use-site overloadかtype-decl site conformanceか、みたいな・・・

tarunon 06-Jan-20 03:29 PM

use-siteじゃなくても、型の要求する関数の宣言箇所でEquatableを条件にしたWTがあれば、一応open existentialで動く。私のコードはそれでもって動いてるからなぁ (edited)

omochimetaru 06-Jan-20 03:32 PM

制約のないT　から実行時に T: P で分岐する事は不可能なのかな？ (edited)

tarunon 06-Jan-20 03:33 PM

それは可能

上の方に貼った動いてる方のコード、がそれを実現してる

あー

正確にはComponentのProtocolでは縛られてるから

関係のない型で縛る必要はあると思う

omochimetaru 06-Jan-20 03:34 PM

どれだ

ああ

そうね、なにか引っ掛けるためのプロトコルが必要

なにもない T だったらってこと。

やはりRuntime APIを使う必要があるな

tarunon 06-Jan-20 03:35 PM

無から有は作れないか〜

omochimetaru 06-Jan-20 03:36 PM

// witness_table* swift_conformsToProtocol(type*, protocol*);

ただこれ使ってもそこから先も工夫が必要なんだよな、witness tableで、どうすんのっていう

tarunon 06-Jan-20 03:36 PM

これが使えたところで==の呼び出しが叶わなければ無駄

今回のハックの激アツだったところは無から==が呼び出せる可能性があったからなのだ

omochimetaru 06-Jan-20 03:37 PM

witness tableから static funcを引っ張ってこないといけない

つまりwitness method callの自作

いや、なんかerasureを用意してそれのinit呼び出しにすればいいのかまあそれもgeneric method callですが

厳しいな、swift calling conventionがC言語から使えないから

マシンごとにアセンブリでレジスタ登録して呼び出さないとダメそう

うーん

swiftselfもswifterrorも関係ないからC言語で辻褄合わせた関数シグネチャ作ったらABIが合う気がしなくもない

tarunon 06-Jan-20 03:48 PM

うーんBaseProtocolの中にこっそり混ぜる分にはアリな気がしてきた>MaybeEquatable

ちょっとこれ無しでValue:Equatableハックは複雑な型だと厳しすぎる

どうせprotocolで引っ掛けてるならやってること一緒なんだよな

tarunon 06-Jan-20 04:05 PM

再現できなかった

全てがGenericsで渡ってるとうまく動く、一回でもExistentialに墜ちるとダメっぽい。じゃあ私のコードはなぜ動いていたの

tarunon 06-Jan-20 05:11 PM

解決しました。 Existentialになった型自身でWTの探索をさせるのがポイントだったようです。一般化した実装をつくりました。 https://gist.github.com/tarunon/85bdeccf8bc8f44b7b27d4974e0a843f

GitHub Gist: instantly share code, notes, and snippets.

omochimetaru 07-Jan-20 01:16 AM

これだと、AnyEquatableのinitのところで、E:Equatableの制約を静的に見てるから

結局制約のないTのパターンのcheckだと無理なのは一緒に見える

tarunon 07-Jan-20 01:17 AM

それはそう、なのでMaybeEquatableを外側に置いて、そこからAnyEquatableを生成する事でその課題をクリアしている

omochimetaru 07-Jan-20 01:18 AM

ああ、出発点(ユーザーが触る方)はそっちか。

これは、extensionのisEqualの中からだと

動的な判定でSelf:Equatableのwhereの方を呼び出せるってこと？

tarunon 07-Jan-20 01:19 AM

そういうことです

omochimetaru 07-Jan-20 01:20 AM

よし、理解あってた

tarunon 07-Jan-20 01:20 AM

公開するProtocolのベースにMaybeEquatableを使う事で、ユーザーサイドで付与したEquatableを使って動作を切り替えることができる

omochimetaru 07-Jan-20 01:20 AM

やはりexistential extension openは魔法的だ

tarunon 07-Jan-20 01:20 AM

魔法ですねぇ

しかもこれ、ちょっと作り方違うと動かないので

omochimetaru 07-Jan-20 01:34 AM

あ〜　簡単にしようとしたら、 MaybeEquatableにSelfが入ってダウンキャストできなくなったｗ

tarunon 07-Jan-20 01:34 AM

でしょw

omochimetaru 07-Jan-20 01:34 AM

でももうちょっときれいにできる気がするなあ

tarunon 07-Jan-20 01:34 AM

AnyEquatableとMaybeEquatableの関係が、この間Twitterで言ってた逆転させるprotocolのテクニックです

型消去を使ってprotocolの宣言を外しつつwtを別の場所に移動させる

omochimetaru 07-Jan-20 01:56 AM

tarunon 07-Jan-20 01:57 AM

私のやつ、public protocolにwtを乗せたくなかったからわけていたのだ

omochimetaru 07-Jan-20 02:01 AM

どういう意味？

tarunon 07-Jan-20 02:02 AM

_isEqualとか__isEqualをユーザーサイドで実装したり呼び出したり、を出来ないようにしたかった

omochimetaru 07-Jan-20 02:02 AM

asAnyEquatable().isEqual()が呼び出せるのは良いのか

tarunon 07-Jan-20 02:02 AM

そこinternalにできるよ

omochimetaru 07-Jan-20 02:03 AM

あ〜

tarunon 07-Jan-20 02:03 AM

AnyEquatableの存在だけをpublicにして、他のすべてを封印できる

omochimetaru 07-Jan-20 02:03 AM

func anyIsEqual　と asAnyEquatable だけが見えてて

tarunon 07-Jan-20 02:03 AM

そういうテクニックですだ

そうそう

omochimetaru 07-Jan-20 02:03 AM

AnyEquatableの機能は使えない

って状態にできるのね。

tarunon 07-Jan-20 02:04 AM

確かにもうちょい減らせる気がしてきたな

tarunon 07-Jan-20 02:11 AM

いらんprotocol減らしてあとは比較対象の方は値しか使わない(関数は利用されてない)のでopenしなくて良さそう

omochimetaru 07-Jan-20 02:14 AM

as? T でいいよね。 (edited)

tarunon 07-Jan-20 02:14 AM

そうね

omochimetaru 07-Jan-20 02:27 AM

う〜ん不思議だ、継承boxを作らないでやろうとすると何かしら詰まる。

tarunon 07-Jan-20 02:29 AM

継承boxが==をキャプチャするのがミソと思われる

omochimetaru 07-Jan-20 02:39 AM

erasureは外側はなくして継承Boxそのままにした。 (edited)

そうか、どうせ公開しないなら外側が要らなくなるのね

omochimetaru 07-Jan-20 02:39 AM

ErasedOpaqueEquatableもpublicだけどopenじゃないからユーザー継承もできないし。

tarunon 07-Jan-20 03:18 AM

継承消せたw

おお

swift51 BOT 07-Jan-20 03:18 AM

true false

tarunon 07-Jan-20 03:18 AM

これが一番短いと思います

omochimetaru 07-Jan-20 03:19 AM

あ〜ｗクロージャねｗ

確かにクロージャってそもそもが型Fに対して

値で実装を分けてるから

ベースクロージャ型と、個別のクロージャ式に対応する型の

アドホックな継承関係なんだよな

tarunon 07-Jan-20 03:19 AM

うむ

omochimetaru 07-Jan-20 03:20 AM

今回はどうせ処理を切り分けたいだけの継承だからクロージャでもいいか。強いて言えば若干デバッグしづらいかな。

tarunon 07-Jan-20 03:20 AM

まあここをデバッグする事はあんまり無さそう

omochimetaru 07-Jan-20 03:21 AM

そうすると、ErasedOpaqueEquatableもなくして、 (Any)->Bool　を返すのもありだな

tarunon 07-Jan-20 03:21 AM

お、なるほど

omochimetaru 07-Jan-20 03:21 AM

func partialApplySelfToIsEqual() -> (Any) -> Bool

tarunon 07-Jan-20 03:21 AM

ヤベェ関数が生えたw

omochimetaru 07-Jan-20 03:22 AM

まあユーザーにこれが見えるのと、ErasedOpaqueEquatableが見えるの、どっちが良いかって択だな

tarunon 07-Jan-20 03:23 AM

typealiasにして誤魔化すのはどうだろう

typealias PartialAppySelfToIsEqual = (Any)->Bool

omochimetaru 07-Jan-20 03:26 AM

ユーザーからするとErasedOpaqueEquatableはその先のisEqualの呼び出しができないけど

typealias PartialAppySelfToIsEqualは、関数としての呼び出しができるという意味では

露出はやっぱり増えてるね

tarunon 07-Jan-20 03:26 AM

確かに

コードは圧倒的に短いな、4ブロックだ

omochimetaru 07-Jan-20 03:27 AM

そういう意味ではさっきのtarunonのやつが露出最小の場合の実装最小な気がする

tarunon 07-Jan-20 03:27 AM

まあでも実質的にisEqual(to:)呼ぶのと変わらんけ

omochimetaru 07-Jan-20 03:27 AM

露出をちょっと許すなら partialApplySelfToIsEqualだと思う

うん。そうね。

tarunon 07-Jan-20 03:27 AM

実行時に軽い方でもいい気がする

ヘッダーから見える世界はこう

綺麗では

omochimetaru 07-Jan-20 03:28 AM

typealiasなのも見えるでしょ？

tarunon 07-Jan-20 03:28 AM

typealiasも見えてるけど

まあ許せる範囲かな

しかしこのテクニック凄いね、今までできなかったことが出来るようになった

omochimetaru 07-Jan-20 03:30 AM

まあMaybeEquatableでマーキングするという作業は残っちゃってるけどね

実行時ダウンキャストで where を復元できるのは面白い。

tarunon 07-Jan-20 03:30 AM

protocol conformingを通してexistentialを作れないprotocolへのダウンキャストを実装する、という手法かな

open existentialと並ぶ革命だわ

omochimetaru 07-Jan-20 03:31 AM

そうだね、PATへのダウンキャストを普通のprotocolを一回挟むとできる

業務だと、

レスポンスの型を登録しておいて

レスポンスの中にあるtypeってフィールドを見て、対応するレスポンスの型を動的にdecodeする、

みたいなパターンで似たような事をしていた

リクエストの型のassociatedtypeからレスポンスの型をジェネリクスで引っ張るのが一般的だと思うんだけど

正常系のレスポンスはそれで良いとして、エラーレスポンスも型付けしたいからそうしてた

tarunon 07-Jan-20 03:34 AM

APIの話だと私の書いたコードだとエラーもあらかじめ型付けしてあってレスポンス同様にデコードしてたな

omochimetaru 07-Jan-20 03:35 AM

普通にやるとエラーをデコードしてる処理を、エラーの種類を足すごとに追加するか、リクエストに対して固定のエラー型にならない？

tarunon 07-Jan-20 03:36 AM

protocol Request { associatedtype Response associatedtype Error }

omochimetaru 07-Jan-20 03:36 AM

そうよね。

tarunon 07-Jan-20 03:36 AM

これで事足りる気がするけど

omochimetaru 07-Jan-20 03:37 AM

let possibleErrorTypes: [APIResponseErrorProtocol.Type] = [LoginError.self, ValidationError.self, ...]

こういう感じに配列で登録しておいてどんな型のエラーも飛ばせるようにした感じ。

tarunon 07-Jan-20 03:37 AM

ほー

enumじゃだめなん

omochimetaru 07-Jan-20 03:38 AM

enumにした場合、結局、そのenumのdecodeを書くところで

JSONのtypeフィールドの文字列を見て、switch-caseで

type文字列ごとに対応するcaseをdecodeするって処理を

書く部分が出てくるでしょ？

tarunon 07-Jan-20 03:39 AM

配列だと出ない？

omochimetaru 07-Jan-20 03:39 AM

でない。

tarunon 07-Jan-20 03:39 AM

omochimetaru 07-Jan-20 03:39 AM

enumだと、

普通にやるとエラーをデコードしてる処理を、エラーの種類を足すごとに追加するか、リクエストに対して固定のエラー型にならない？

↑で書いたように、エラーの種類を足すごとに case を書かないといけない

配列に入れておいて、

protocol APIResponseErrorProtocol: Decodable { static var typeName: String { get } }

↑こうしておいて、

あとはループしながらtypeNameの対応がみつかったらDecodableでdecode

って形にすると、エラーの型を定義して、possibleErrorTypes配列にメタタイプを追加していくだけで

decodeのcaseの追加はしなくて良くなる。

tarunon 07-Jan-20 03:41 AM

そうすると取り出す側はキャストにならない？

omochimetaru 07-Jan-20 03:41 AM

取り出す側はキャストになる。

tarunon 07-Jan-20 03:41 AM

Error型だから別にいいやって感じか

omochimetaru 07-Jan-20 03:41 AM

でもそれは、 do { } catch { } してるとき、いつもそうだから。

てか、結局の所throwすることになって、画面レベルの根っこのcatchで分岐する感じ。

エラーレスポンスがそのままアプリの中のエラーとしてthrowされてくる状態。

tarunon 07-Jan-20 03:42 AM

なるほどね

omochimetaru 07-Jan-20 03:42 AM

Error型だから別にいいやって感じか

そういうことやね (edited)

tarunon 07-Jan-20 03:43 AM

私が書いたのはAPIの関数の返り値はAsync<Result<T,E>>だから、型がしっかりしてるモチベが高いから

あとエンドポイントごとにエラー型を明示的に定義したいモチベもあったのでそういう作りになっていたのだ

enumでもデコード処理をループで書くのは昔作ったから、それでもいい気はしたけど、まあ色々根底が違いそうである

omochimetaru 07-Jan-20 03:46 AM

enumでもデコード処理をループで書く

このケースで同じことをやってそうな気がする

tarunon 07-Jan-20 03:47 AM

そんな気はするね

今回の価値はextension Tと、extension T where Self: Uが、きちんと期待通りに動くケースを一般化できたことだな

omochimetaru 07-Jan-20 03:49 AM

それで、そのループするために、メタタイプを登録していくと、要素が APIResponseErrorProtocol.Type になるから、 existential openを使わないと init(from decoder: Decoder) が呼べないという話

tarunon 07-Jan-20 03:50 AM

なるほどね

omochimetaru 07-Jan-20 03:51 AM

今回の価値はextension Tと、extension T where Self: Uが、きちんと期待通りに動くケース

そうね

protocol requirementsにエントリがあってwitness tableに載ってると、 existential extensionのselfからのメソッド呼び出しでディスパッチできる。

tarunon 07-Jan-20 03:55 AM

try swiftのltにもっていこうかしら、このサイズなら収まりそう

omochimetaru 07-Jan-20 03:59 AM

Equatableにダウンキャストできないよね、ってところから流れで行けばまとまりそう

ただexistential openが結構深いトリックであるってことはスルーされそうだ

tarunon 07-Jan-20 04:01 AM

聴衆はそもそもGenericsとExistentialの違いもアヤフヤな人が多い想定なので、敢えてそこは解説しないでいいと思う

omochimetaru 07-Jan-20 04:03 AM

できることの結果だけ話すってことね。

tarunon 07-Jan-20 04:04 AM

条件と結果、一般化できるぞいというところまでだな。

omochimetaru 07-Jan-20 04:04 AM

たしかにタルノンが発表する時ってそういう構成の事が多いな

SPMがCとSwiftの混じったターゲットを作れないので微妙にシンボルが公開されちゃってますが、手でリンクすればisEqualだけ公開するようにできるはず

こんな感じで使えます https://github.com/kateinoigakukun/AnyEquatable/blob/master/Tests/AnyEquatableTests/AnyEquatableTests.swift

C経由でSwiftRuntimeを無理やりこねくり回すの、禁断の果実感あって良いですね

kateinoigakukun 07-Jan-20 12:26 PM

ミソはwitness methodの呼び出しをSwift側に移譲してる部分です

tarunon 07-Jan-20 12:26 PM

これはC部分はどうしてもSwiftだとかけない感じですか？

kateinoigakukun 07-Jan-20 12:27 PM

書けそう！

tarunon 07-Jan-20 12:27 PM

書けない理由が特に無さそうに見えたので

kateinoigakukun 07-Jan-20 12:27 PM

最初はもうちょっと込み入ったことをしようとしてたんですけど結局シンプルにできたのでフルSwiftで書けそう

あー、フルは無理でした

ProtocolDescriptorをシンボル経由で抜いてるんですけど、そこで@_silgen_nameが使えなかった…

tarunon 07-Jan-20 12:30 PM

なるほど

kateinoigakukun 07-Jan-20 12:30 PM

いや、dlsymすればいいのか (edited)

tarunon 07-Jan-20 12:31 PM

dlsymはXcode環境下で謎に動かない場合があるので

動くかチェックは必要そう

動かない場合も退避先にMachO使えるし何とかなるんじゃないかな

Swift関数にメタタイプとWTを差し込むためにはC側から呼んでやらないとダメなんですよねー

omochimetaru 07-Jan-20 01:21 PM

あれ、やろうと思ってたらもうできちゃった？

tarunon 07-Jan-20 01:22 PM

@convention(c)をつけた関数ポインタの首を挿げ替えて無理やりコールは出来ないかな

kateinoigakukun 07-Jan-20 01:29 PM

import Foundation let RTLD_DEFAULT = UnsafeMutableRawPointer(bitPattern: -2) @_silgen_name("foo") func foo() {} let fooPtr = { dlsym(RTLD_DEFAULT, "foo")!.assumingMemoryBound(to: (() -> Void).self) }() fooPtr.pointee

これがクラッシュするんですよね、デリファレンスした瞬間にbad accessになる (edited)

@convention(c)どこにもつけられなくて困った

norio_nomura 08-Jan-20 09:07 AM

こんな感じにすると@convention(c)使える。

import Foundation public func isEqual(_ lhs: Any, _ rhs: Any) -> Bool { let lhsType = type(of: lhs) let rhsType = type(of: rhs) guard lhsType == rhsType else { return false } guard let witnessTable = swift_conformsToProtocol(lhsType, EquatableProtocolDescriptor) else { return false } let theType = unsafeBitCast(lhsType, to: UnsafeRawPointer.self) return withUnsafePointer(to: lhs) { lhsPtr in withUnsafePointer(to: rhs) { rhsPtr in AnyEquatable_internalIsEqual(lhsPtr, rhsPtr, theType, witnessTable) } } } @_silgen_name("swift_conformsToProtocol") func swift_conformsToProtocol(_: Any.Type, _: UnsafeRawPointer) -> UnsafeRawPointer? func load<T>(symbol: String) -> T { if let sym = dlsym(dlopen(nil, RTLD_LAZY), symbol) { return unsafeBitCast(sym, to: T.self) } let errorString = String(validatingUTF8: dlerror()) fatalError("Finding symbol \(symbol) failed: \(errorString ?? "unknown error")") } let AnyEquatable_internalIsEqual: @convention(c) (UnsafeRawPointer, UnsafeRawPointer, UnsafeRawPointer, UnsafeRawPointer) -> Bool = load(symbol: "AnyEquatable_internalIsEqual") let EquatableProtocolDescriptor: UnsafeRawPointer = load(symbol: "$sSQMp") @_silgen_name("AnyEquatable_internalIsEqual") func _internalIsEqual<T: Equatable>(_ lhs: T, rhs: T) -> Bool { return lhs == rhs }

(edited)

しかし、LinuxだとシンボルAnyEquatable_internalIsEqualを見つけられないな。

kateinoigakukun 08-Jan-20 12:38 PM

なるほどなるほど

Linuxでシンボル見つけられないのはなんでだろう…

そもそも、フルSwiftで書くためにわざわざダイナミックリンクするのは微妙な気がしてきた (edited)

swift52ボット、新規で作るか、swift40ボットを動かしてるHeroku環境を流用してしまおうか、迷う。

Kishikawa Katsumi 09-Jan-20 03:46 AM

どういう違いがあるんですか？

norio_nomura 09-Jan-20 04:00 AM

一つのボットに一つのherokuアカウントを使う構成なのです。

流用すればアカウントを増やさずに済む。swift40ボットは無くなるけど。

ボットを使う側に対しては「swift40ボットにまだ生き残って欲しいか？」という質問になりますね。

tarunon 09-Jan-20 04:07 AM

4系は4.2が生きていれば良さそうに思えます。Xcodeもそうだし。

exit status: 1 with stderr:

<stdin>:1:1: error: non-nominal type '(Int, Int)' cannot be extended extension (Int, Int) {} ^ ~~~~~~~~~~ Nominal types -------------- In Swift, a type is considered a nominal type if it is named. In other words, it has been defined by declaring the type somewhere in code. Examples of nominal types include classes, structs and enums, all of which must be declared before using them. Nominal types are an important concept in Swift because they can be extended, explicitly initialized using the 'MyType()' syntax, and may conform to protocols. In contrast, non-nominal types have none of these capabilities. A non-nominal type is any type which is not nominal. They are sometimes called “structural types” because they are usually obtained by composing other types. Examples include function types like '(Int) -> (String)', tuple types like '(Int, String)', metatypes like 'Int.Type', and special types like 'Any' and 'AnyObject'. Whether the name of a protocol refers to a nominal or non-nominal type depends on where it appears in code. When used in a declaration or extension like 'extension MyProtocol { … }', 'MyProtocol' refers to a protocol type, which is nominal. This means that it may be extended and conform to protocols. However, when written as the type of a constant or variable, 'MyProtocol' instead refers to a non-nominal, existential type. As a result, code like 'let value: MyProtocol = MyProtocol()' is not allowed because 'MyProtocol' refers to a non-nominal type in this context and cannot be explicitly initialized.

exit status: 1 with stderr:

<stdin>:2:11: error: protocol 'P' can only be used as a generic constraint because it has Self or associated type requirements func f(p: P) {} ^ Using Protocols with 'Self' or Associated Type Requirements Protocols in Swift may be used as types, as part of a generic constraint, or as part of an opaque result type. // CustomStringConvertible can be used as a type. func foo(bar: CustomStringConvertible) { /* ... */ } // ...or as a generic constraint on 'T'. func bar<T: CustomStringConvertible>(baz: T) { /* ... */ } // ...or as part of an opaque result type. func baz() -> some CustomStringConvertible { /* ... */ } While all Swift protocols can be used as generic constraints and as part of opaque result types, not all protocols can be used as types in general. Specifically, if a protocol has a requirement which references 'Self' or an associated type, it cannot be used as a type. One such protocol is 'Identifiable', which has the requirement 'var id: ID { get }', where 'ID' is an associated type. As a result, the following code is not allowed: func foo(bar: Identifiable) { /* ... */ } // error: protocol 'Identifiable' can only be used as a generic constraint because it has Self or associated type requirements Protocols like 'Identifiable' which have 'Self' or associated type requirements cannot be used as types because such types would rarely be useful in practice. They would be unable to allow use of 'Self' or associated type requirements like 'var id: ID { get }' because the associated type is not specified. When working with protocols having 'Self' or associated type requirements constrained generics, opaque result types, or manual type erasure is sufficient to support most use cases.

let foo = Array {} print(type(of: foo))

Array {} compiles to array of type [() -> ()]

So I just found this out. Not sure if it's a bug or somehow expected behavior. let foo = Array {} The code above works, and foo is inferred to be of type Array<() -> ()> aka [() -> ()] with a single element inside: an empty closure () -> () (which I assume is our {}). Digging deeper into which initializer is responsible for the instantiation,...

この前のwaiwaiでも話題になった、 Trailing Closure のラベル省略が良くない事例だと思う。

omochimetaru 16-Mar-21 04:46 AM

init(arrayLiteral:) って Array Literal 用のinitだから、

リテラルが書いてある場合もしくは、ラベルが書かれている場合しか、解決しないのが良さそう？

ラベルが書かれていない場合、というケースはTrailing Closureを使ったときしか生じないだろうけど。

koher 16-Mar-21 04:49 AM

うん。普通はラベルがあるから意味わかるんだけど、 Trailing Closure になるとラベルが省略されて意味わからんくなってる。

omochimetaru 16-Mar-21 04:49 AM

意味わからなくなるのは幅広い問題ですね。

koher 16-Mar-21 04:49 AM

↓なら問題ないはず。

let foo = Array arrayLiteral: {}

omochimetaru 16-Mar-21 04:49 AM

それってIDEが解決するのは駄目なんだろうか

今年のGSoCのテーマにもなってて。

テキストデータとして書かれてなくても arrayLiteral: が Xcodeによって表示されてれば、問題は解決する。

koher 16-Mar-21 04:50 AM

source breaking すぎてもはや↑の変更はできないだろうけど、ラベルを許す、ラベルなしは警告とかならできそう。

型推論の結果とかもそうする。

tarunon 16-Mar-21 07:15 AM

根本的にはOptionalがtagged unionであるということと、T?とTのサブタイピングを認めてかつTとUがサブタイピング関係があるときにT?とU?のサブタイピングも認める、ということをしちゃうと

型理論に優先順位のルールを加えなきゃいけなくなるが、人間の認知はここまで追い付かないので

文脈によってサブタイピングがあって欲しい場合とサブタイピングを認めたくない場合が混在してしまい

人間はそれをバグと認知してしまう

ああ、すいません、わかっていたはずなのですが、 unique でない → Logic Failure → ! みたいなステップで思考がバグってました。

uniqueKeysWithValues に渡すものがおかしいのは Logic Failure でいいと思うんですが、ユニーク化のときにユニークでない場合に Recoverable なエラーハンドリングができる簡単な方法があるといいですよね。 uniqueKeysWithValues は割と踏みがちな気がするので・・・。

元の型が2重または3重オプショナルの場合エンコード結果から元の型はわからないけどそれは問題ないんですよね？

omochimetaru 05-Jun-21 04:52 PM

型のほうは case名のキーの a で残ってるんでいいのです

Kishikawa Katsumi 05-Jun-21 04:53 PM

まあそうか。オプショナルは元々のEnum含まない使用でも広く受けることできますしね。

omochimetaru 05-Jun-21 04:53 PM

一番外側の none はキーレス、一番内側のsomeは値、その中間レベルの .some の中の .none は全部 null につぶれてしまうようだ。

中間の null は正しくデコードできるのか・・・？

@swift-nightly

import Foundation enum E: Codable { case a(Int???) } let decoder = JSONDecoder() let json = """ [ { "a" : { } }, { "a" : { "_0" : null } }, { "a" : { "_0" : null } }, { "a" : { "_0" : 1 } } ] """.data(using: .utf8)! let value = try decoder.decode([E].self, from: json) dump(value)

omochimetaru 05-Jun-21 04:55 PM

駄目だな。デコード側はキーレスとキー有りのnullの区別もできない。

エンコード側は３種類の出力があるけどデコードは２種類（最も外側noneと最も内側some)しか扱えないと。

Kishikawa Katsumi 05-Jun-21 04:56 PM

意図した挙動じゃない気がしますねえ。

エンコードのほう。

キーがあるnilで良さそうですけどキーがないほうが自然ですか？

私の印象はパッと見ての印象だから違うかもしれない。

omochimetaru 05-Jun-21 04:58 PM

codableってそうなんですよね、キーも出さない

SE-0295のenumのassoc valueのoptionalの扱いについては文書で触れてないけど、 (edited)

Kishikawa Katsumi 05-Jun-21 05:00 PM

なるほど。もともとのCodableはnilのときキーごと消すんでしたか。

まあそうすると "_0" : null はnullという値があるっていう表現になるから合ってるのか。

まあJSONの仕様を超えてるし難しいところだ。

例えばP1がpublicかつ外部モジュールで extension Int: P1 {} された場合、 X: P1 が成り立つケースはあるがinternalな場合はエラーでいい気がする

jsonのkeyは文字列であることが必須で、Stringは特別に文字列であるとみなされてkeyValueになるけど、RawRepresentableはそこ特別にハンドルされてなかった気がする Swift的にはArrayからDictionaryに戻せるのでそっちの動きが優先されてる

omochimetaru 16-Aug-21 07:24 AM

正しいというかそういう仕様だよ

一般のDictionaryのcodingは、[k1, v1, k2, v2, ... ]だから。

以前のものと違う点 // 追加 - リプライによるメンション元の追跡 - 同じボットへの複数コマンド発行(-Oと-Ononeの比較とか。) - 公開スレッド／非公開スレッドチャンネルに対応 // 未実装 - インポート可能モジュールの提供(swift-NIOとか) - 長文ログのアップロード (edited)

とりあえず @swift55 だけが新しいコードで動いてて、それ以外は以前のままです。

In -Ounchecked builds, the optimizer may assume that this function is never called.

仕様上は消えてもいいのかな。

omochimetaru 16-Sep-21 04:35 AM

多分クラッシュする部分は残しておいたほうが

フロー解析でデッドエンドが検出できるんで得ですよね

何も考えずに全く関係ない次のラベルにフォールスルーするコードになっちゃってると

むしろ元のコードよりフローの繋がりが複雑になってしまう

LLVM IR におけるBasicBlockの接続グラフが変わっちゃうというか。

precondition と違って preconditionFailure は分岐して使うことが前提となってるし、そうかも。

On the behavior of variables in top-level code

The variables in top-level code behave weirdly. They are declared in the global scope, but are initialized serially, like local variables in a normal function. This allows some interesting pieces of code to compile, such as: print(x) var x = 32 This program will print 0. The basic value types are automatically initialized, so they have a value...

norio_nomura 04-Oct-21 02:47 AM

他にも、ボットとSwiftコンパイラが同じコンテナ内の同じアカウントで動いてる故に起こせる挙動（ボットプロセスをkillするとか）もあるだろうけど、Herokuのコンテナを再起動すれば直る様なものは対策しないと思う。

omochimetaru 04-Oct-21 02:48 AM

ボットとSwiftコンパイラが同じコンテナ内の同じアカウントで動いてる

なるほど、出発点がそういう話なのか。

norio_nomura 04-Oct-21 02:51 AM

いかにHerokuへお金を払わずに済ますかという縛りプレイ。

僕が提供してるボットの稼働には僕の人件費以外、使用量に応じたコストはかからないので、じゃんじゃん使ってください。 (edited)

ボットとSwiftコンパイラが同じコンテナ内の同じアカウントで動いてるのは、これはHerokuの制限なので今も変わらず。

norio_nomura 04-Oct-21 02:58 AM

Herokuもお金を払えば、コンテナ分離構成で作れます。

一応今後の予定としては、たぶん、古いSwiftバージョンボットの非常駐化を優先します。

今まで僕のGmaiアドレスで<name>+...@gmail.com形式のエリアスを使って、Herokuのアカウントをボット毎に作ってきました。 (edited)

しかしswift55ボットのHerokuアカウントを作る際に、メールアドレスが弾かれる様になり作れなかったので、swift40ボットのHerokuアカウントを流用しました。

ボットを非常駐化すれば、Herokuアカウントを減らせるかなと。

omochimetaru 04-Oct-21 03:09 AM

Heroku無料プラン縛りプレイ難しいｗ

norio_nomura 04-Oct-21 03:10 AM

アカウントBANではなく、新規作成を弾いてくるのが巧妙ですw

まあ、Gmailエリアスではなく新規にGmailアカウントを作れば解決しそうですが、これも縛りの一環ということで。

HerokuのTOSを確認した限り、複数アカウント作成に関する制限は明文化されてないのですよね。

やっぱり Foo | Nil と Either<Foo, Nil> を混ぜて扱うこと自体に無理がある・・・。 Codable と JSON の Foo?? とかも。色んなところで歪みが出るのは避けられなくて、できるだけ普段目に触れないところで出すようにしてるけど、普段目に見えないからこそ不意をつかれた感じになる。

一方で、 Obj-C 連携とか、普段の使い勝手（たとえば Optional に代入する度に .some を書くべきなのか）とかを考えると仕方ないよなぁ。仮に全部 Foo | Nil に寄せると IteratorProtocol の next が（ Element が Optional のときに）表現できないとかそれはそれで問題があって、とはいえ Foo | Nil と Either<Foo, Nil> を適切に使い分けるのもハードルが高いし、どれを取っても一長一短。なので、 Swift は理論的なきれいさよりも実用上の使いやすさをとって、その分生じる歪みをできるだけ目立たないところで消化するという選択なんだろうなぁ。

ちょうど最近トップレベルの変数宣言についてアクティブな議論がありました。 https://forums.swift.org/t/on-the-behavior-of-variables-in-top-level-code/52230

On the behavior of variables in top-level code

The variables in top-level code behave weirdly. They are declared in the global scope, but are initialized serially, like local variables in a normal function. This allows some interesting pieces of code to compile, such as: print(x) var x = 32 This program will print 0. The basic value types are automatically initialized, so they have a value...

グローバルなmutable変数へのアクセスは一律unsafeになっていてMutexを使わない限り非安全な操作として扱われますね。ここはSend traitを実装していたとしても変わらないです

await 以降の処理がグローバルなコンテキストで律速してる？

暗黙globalActorのQueueが2個のときと1個のときがあって2個のときはバラけるな (edited)

2個以上あるときは同じ Nanika に対して並列に f を呼び出すと壊れるけど、そもそも呼び出しの時点で何も安全性が保証されてないのでそこを保護してもしょうがないのか

あれ、実行時エラーじゃなくてコンパイラのクラッシュになった

5.5と5.6で挙動違うし、macとLinuxでも挙動違っててわけわからん

~~Linuxにおけるコンパイラのクラッシュは https://discord.com/channels/291054398077927425/430242233468452865/932567619192619040 と同じか？~~ 5.5.2コンパイラがクラッシュしてないので微妙に違いそう (edited)
